Overhaul or replacement of the engine, what to choose?

When approaching a mileage of 150,000 km, the VAZ 2110 engine starts to junk. This period is considered optimal for overhaul of the power unit. The timely replacement of consumables and their quality have an important effect on the engine resource.

The figure of 150,000 km of run can change downward if service terms are not observed and the quality of oil and filters is poor. To postpone the overhaul, it is necessary to diagnose the engine.

The technology of carrying out an overhaul of the engine requires the removal of the engine from the car

Overhaul of the engine is the restoration of units and parts of the power unit to the factory parameters. To compare the performance of the engine used with the factory specifications, you will need special measuring instruments.

Before starting the overhaul, you must read the repair instructions and estimate the scope of work. The repair process itself is not complicated, but it takes a lot of time.

Overhaul is carried out with the constant occurrence of engine malfunctions. First, you need to check the engine yourself and replace the failed parts. If it is not possible to eliminate the malfunction of the power unit or it reappears soon after elimination, a major overhaul is required.

By the following signs, you can determine the need for overhaul of the power unit:

  • Increased oil consumption - piston rings or valve guides may be out of order. The first step is to check for cracks leading to oil leaks.
  • Engine noises and knocks. A possible cause of the malfunction is the failure of the connecting rod or main bearings.
  • Loss of engine power. There are many reasons for the loss of power. Unstable engine performance may be due to lack of compression.
  • Engine failures.

If several signs appear together, an urgent overhaul is required.

You should not purchase replacement parts in advance. First of all, the engine is disassembled and the condition of its elements is checked. In the absence of equipment, the condition of the parts is checked at the service station. In conclusion, experts indicate which parts to change during overhaul and what can be restored.

The number of motorists in Russia is growing rapidly. According to sociologists, every second Russian citizen will have his own car in three years. According to a poll conducted by the All-Russian Public Opinion Research Center, 59% of car owners own cars of domestic production.

The VAZ 2110 sedan is rightfully considered the ancestor of a new generation of front-wheel drive Russian cars, the serial production of which was started in 1996. Distinctive features of this model are the use of galvanized metal for body parts, ventilated brake discs, bonnet mount on gas stops. The device of this car is based on electronic control, which allows the driver to control the operation of the machine's mechanisms. Probably, it was these innovations that allowed the VAZ 2110 to become a fairly popular model among Russian motorists.

Every car owner knows that it is necessary to monitor the technical condition of the car, regularly carry out preventive procedures, which will extend the life of the vehicle.

The most important part of any car is the engine, it is he who requires increased attention. The car enthusiast should not ignore the high oil consumption in the car, the decrease in its power, noise or knocking.As a rule, all these facts indicate an engine malfunction, but this does not mean that it needs to be changed urgently. Perhaps you just need to overhaul the VAZ 2110 engine.

Diagnostics using a computer system and the availability of qualified specialists in the car service personnel helps to carry out troubleshooting at the proper level.

Overhaul of a VAZ 2110 engine, as a rule, consists of a number of stages:

- dismantling of the engine itself;

- removal of various kinds of contaminants from its surface;

- disassembly and flushing of parts;

- identification of engine defects (measuring instruments are used here, which allow you to accurately determine the degree of wear, deformation of parts);

- checking the body parts for cracks (for this, pressure testing equipment is used);

- detection of knocks during operation of engine mechanisms and measurement of pressure in the lubrication system (low pressure - a signal of a breakdown);

- replacement of hoses, drive belts, thermostat and water pump with new ones;

- checking the condition of the radiator (if a leak is found or the permeability is impaired, then it must be replaced);

Based on the information received and comparing them with the indicators established by the manufacturer, it is determined whether repair is possible and in what way, or a decision is made to replace parts.

For the owner of the vehicle, the cost of the overhaul of the VAZ 2110 engine is of great importance. The price largely depends on the type of engine, on the manufacturer, and on the nature of the malfunction itself. Note that the same factors affect the period of repair work.

In conclusion, we recall that high-quality and prompt overhaul of the VAZ 2110 engine is possible provided that the auto center has experienced mechanics and modern diagnostic equipment, so you need to responsibly approach the issue of choosing a repair shop.

Repairing the VAZ 2110 engine, like any other model of the car, is not an easy job, but still performed. If you are at least a little versed in the technique, then you will be able to perform it. To carry out repairs, you must at least disassemble the engine. We bring to your attention a hint on how and in what sequence to carry out such work.

3. Remove the tension roller, camshaft drive belt and spacer washer that is installed under the tension roller.

4. Remove the toothed pulley from the camshaft.

5. We unscrew four bolts, three of which are attached to the water pump. We unscrew the fastening nut on the rear cover of the camshaft drive belt and remove the cover.

6. To remove the water pump, insert a screwdriver between the block and the pump casing flange and thus slide it out of its seat. After completing these operations, we remove the water pump.

7. Remove the head from the cylinder block.

8. Unscrew the bolts (16 of them) securing the oil sump, then remove it together with the gasket.

9. Unscrew the bolts (3 of them) fastening the oil receiver and remove it. Note that there are spring washers under the bolt heads.

11. Then rotate the crankshaft so that the piston that is being removed hits the BDC (bottom dead center). It is necessary to unscrew the two fastening nuts to remove the connecting rod cover.

12. Now remove the connecting rod cover.In the case when it is difficult to dismantle the cover, you can first touch it with light blows of a hammer. It may be that the number of the cylinder on the cover will be invisible, in which case the cover should be marked with the number of the cylinder.

13. Using the hammer handle, push the connecting rod into the cylinder, then carefully remove the piston with the connecting rod from the cylinder. In the process, you need to make sure that the lower head of the connecting rod does not touch the cylinder mirror, as this can damage it. Remove the rest of the pistons in the same way.

14. If it is necessary to remove the piston from the connecting rod, then we mark it with the cylinder number so as not to confuse them during installation. On the connecting rod, the same must be the cylinder number: if it is not visible, then we mark the connecting rod.

16. Unscrew the bolts (there are 6), remove the crankshaft rear oil seal holder and gasket. Remember that there are spring washers under the bolt heads.

17. From the crankshaft, remove the toothed pulley. In the case when the key does not sit tightly in the groove of the shaft elbows, we must take it out so that it does not get lost.

18. Unscrew the six bolts, under the heads of which there are spring washers, and remove the oil pump and gasket.

19. We unscrew the mounting bolts on five caps (each with 2 bolts) of the main bearings.

21. Remove the crankshaft of the VAZ 2110 car.

22. We carry out the removal on the middle support of the persistent half rings of the crankshaft.

23. If it is not planned to replace the liners, then as they are removed, we take them out of the block beds and from the main bearing caps.

24. On the non-working side, we mark the inserts relative to the beds and covers.

25. If there is a need to remove the engine mounts and generator brackets, unscrew the bolts (3 pieces) of their fastening and remove the supply pipe of the water pump by unscrewing its fastening.

26. Remove the piston rings using a special puller. If there is no such device, then remove the rings from the piston, carefully opening the ring locks.

27. Remove the oil scraper ring expander spring from the engine piston.

28. The retaining rings that hold the piston pin are removed from both sides of the piston. Recesses are provided in the piston bosses for easy removal of the rings.

29. Using a suitable mandrel, push the pin out of the piston, then remove the piston from the connecting rod.

30. Take out the inserts from the connecting rod and its cover. If they remain on the crankshaft, remove them from the shaft. If the replacement of the liners is not required, then as they are removed, we mark them with respect to the numbers of caps and connecting rods.

This completes the process of disassembling the VAZ 2110 engine. Successful completion of the renovation.
